STEAM-TRAP.

Specification of Letters Patent.

Patented Feb. 12, 1918.

Application filed December 8, 1.916. Serial No. 135,771.

To all whom it may concern Be it known that 1, Com S'rroiiLn, a citizen of the United States. and a resident of Indianapolis, county of Marion, and State of Indiana, have invented a certain new and useful Steam-Trap; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to improve and simplify the construction and operation of automatic vacuum valve mechanism for radiators, steam heaters and the like.

One feature of the invention consists in so arranging the parts of the device as to make it symmetrical, smooth surfaced, and compact.

Devices of this kind heretofore have had parts projecting considerably over the body of the device to a position which rendered them annoying in handling them and to users, and also unsymmetrical and ugly.

Since these devices are used at residences and olfices on radiators, this feature of the invention is of considerable importance and is attained herein by substituting for the upper portion of the steam trap heretofore employed, a flat top suitably chambered as herein set forth and providing in the wall of the body of the device. a suitable passageway communicating with the chamber in the top.

Another feature of the invention consists in so chambering such top that the chamber therein will always register with the pas sageway in communication with the same for the escape of air from said tube in any position assumed by the top while screwing it in place.

In other words, the top is so chambered that it is unnecessary in screwing it into place to stop it at any certain position. All thatis required is to screw it down tightly. In devices of this kind heretofore the parts had to be carefully adjusted to cause them to register with each other so as to operate. Hence it has been necessary heretofore to bolt or otherwise secure the top in only one fixed position and it could not be screwed on.

Another feature of the invention consists in providing the top with an annular chamber near the external periphery of the top and in communication with a port which is controlled by the float actuated valve, so that the chamber in the top can immediately and directly connect with a discharge pas. sageway leading to an outlet at the bottom of the device, while heretofore the discharge outlet has been located on the side of the device where it was in the way and the vacuum pipe connected with it was also in the wav.

The full nature of this invention will be understood from the accompanying drawings and the following description and claims:

In the drawing Figure 1, is a central vertical section through the device. Fig. 2 is a horizontal section on line 2-2 of Fig. 1. Fig. 3, is a horizontal section on line 3--3 of Fig. 1.

There is shown in the drawings a cupshaped vessel or casing 10, closed at its lower end and open at its upper end and internally threaded at 11 in its upper end and the top 12 has an annular flange 18 extending centrally and downwardly there from so as to screw into the top of the easing 10, with the outwardly extending portion of the top fitted tightly upon the top of the wall of the vessel 10. There is a nut 13 extending centrally upward from the top 12 whereby a wrench can be applied for tightening and releasing the top on the vessel.

The inlet port 1 1 is integral with the side of the vessel 10 and from the inlet port a passageway 15 leads up to an inlet port 16 discharging into the upper portion of the vessel 10 and into the chamber 17 in said. vessel or casing.

The discharge outlet 18 is below the vessel 10 and integral therewith and in communication with a discharge passageway 19 leading from the top down the outer side of the vessel 10. The top 12 has an annular chamber 20 near its outer periphery and located so that it is always in communication with the discharge passageway 19, regardless of just how the top may be positioned when screwed down upon the vessel 10. The annular chamber 20 in the top is in connection with a central chamber 21 in the top through two oppositely located openings 22 and 23. There is also a central opening 24 in the bottom of the top 12 through a downward extending annular collar 25 centrally located, as seen in Fig. 1. Into this collar there is screwed a sleeve 26 with an outwardly extending packing ring on it adapted to abut agains the bottom of.

the collar. A valve seat 27 is screwed into the upper portion of the sleeve 26 so as to lie within the opening 24 in the bottom of the top 12. This valve seat has a central port 28 communicating with the central chamber 21 in the top 12.

Within the vessel 10 there is the usual bucket-shaped float 30 arranged to extend slightly above the bottom of the port inlet 16. The usual valve stem 31 is secured centrally to the bottom of this float so that its lower end will rest upon a lug 32 in the bottom of the vessel 10 and its upper end would extend upward through the float and above the top thereof to a point near the top of the vessel '10. The upper end of the valve stem 31 is tapered to form a valve 33 adapted when the float rises to engage the valve seat 27 and close the port 28. The valve has a groove 37 in it for the escape of air.

The valve stem is held and guided by cross pieces 34 extending across the tube 35 the upper end of which is screwed on and is supported by the sleeve 26, and the tube extends downward almost to the bottom of the float. There is an air port 36 through the tube 35 just above the top of the float when it is down. i

In operation, as the condensation water enters through the inlet, it will gradually fill the chamber 17 of the vessel 10, and when the water rises high enough in the vessel 10, it will cause the, float to rise and close the port 28 leading to the chamber in the top of the device.

As the vessel fills the air will escape through air port 36 and groove 37 in valve 33 into the top chamber 21, port 23, chamber 20, passageway 19 and discharge outlet 18. After the water accumulates in chamber 17 sufliciently it will overflow into the float and when enough water has entered the float, the float will descend and open the port 28.

The invention claimed is:

1. A vacuum valve mechanism for radiators and the like including a vessel having a condensation chamber with the upper end open, a top adapted to screw thereon having an inlet port centrally located and an annular chamber in communication with said port, a discharge passageway in said vessel in communication with the annular chamber in said top regardless of the angular position of the top, and a float controlled valve vithin the device for controlling the port in the top thereof.

2. A vacuum valve mechanism for radiators and the like including a vessel having a condensation chamber therein with the up per end open, a top adapted to screw on the upper end of the vessel with. an inlet port centrally located in it and an annular cham- Copiesof this patentmay be obtained for five cents each. by addressing the Commissioner,oflatents,

ber in communication with said port, and a discharge passage extending down on the outside of said vessel and discharging below the ressel and with the upper end of said passage in comn'iunication with the annular chamber in the top regardless of the angular position of the top, and a float controlled valve for closing the port in the top.
